GPT-5.5 Not Showing in Codex (Windsurf Extension) with ChatGPT Pro
OpenAI Developer Community
May 4, 2026
Hello everyone,
I’ve been developing on Windsurf for a while now. Two days ago, I installed the Codex extension (version 0.5.78) for the first time. Initially, I was using it with my ChatGPT Plus account, but I upgraded to ChatGPT Pro ($200/month) specifically to access more powerful models, especially GPT-5.5.
Right now, I do have access to several models, including GPT-5.4, with different reasoning levels which is great. However, I don’t see GPT-5.5 available anywhere.
I’ve already tried logging out and back in, updating everything, checking settings, and restarting Windsurf, but nothing changed.
So my questions are:
* Is it normal that GPT-5.5 is not available in Codex (Windsurf extension), even with a ChatGPT Pro account?
* Or did I miss something in the setup or configuration?
My goal is really to stay within Winsurf using Codex, but with access to the most powerful models available.
Thanks in advance for your help
